I have tried the Tea Brewer and I LOVE IT! For one the teas they sent are great, for two they are reusable and three they are perfect for camping! I'm in the US and it's hard to find them I just managed to find the 3 pack once at my local REI. I've been reusing the bags with my own tea but they are getting pretty beat up. Hopefully they will be easier to find in the future or maybe see a sturdier tea pot release.
